Determine the volume of a body weighing 15 kg if the density of the substance from which it is made is 800 kg / m3.

Body volume can be calculated using the formula:
V = m / ρ, where V is the required volume of the body (m³), m is the mass of the body (m = 15 kg), ρ is the density of the body (ρ = 800 kg / m³).
Let’s calculate the required body volume:
V = m / ρ = 15/800 = 0.01875 m³ = 18.75 dm³.
Answer: The volume of the body is 18.75 dm³.
